APrARATUs Ami ARTICLES roR WAVING HAIR.

Application led February 20, 1924*l Sierial No. 693,974.

''nis invention relates to devices or apparatus .and articles for waving hair, and aims to provide improvements therein.

The invention provides a device or apparatus which produces a quicker and better wave than heretofore produced. It provides a device less liable tobe injurious to the hair-r dresser using the device and the person whosel .hairis being' waved, than those heretofore used. The device has more mild action on the hair, the hair having a better after condition than when waved v by devices previously in use.

from heat than with prior devices or appara-` tus.

Y The invention'fu'rther provides a device or for use, andl which is of al nature which may be used once and thrown away, thereby providing a sanitary and labor saving article'. d

The invention further provides a device or apparatus in which danger from electric shocks and danger from short circuits is practically eliminated.

Several embodiments ofthe invention are illustrated in the accompanying drawings, in which Fig. 1 is'a vertical sectional view of one embodiment of the deviceand article.

` The waving cany be carried out by the1 present invention with-considerably less current and with considerably less discomfortl vtion,.showirig the mannerlof use voit' the in- Fig. 14' is a diagrammatic viewof the apparatus comprising a plurality of Waving devices.

Referring to said drawings, numeral 10 designates an' electrical heater, and 15 designates an envelope of any suitable kind' in whlchthe heater 10 is contained. 20 designates Ameans for' containing or fholding moisture,

adapted to be vaporized within the envelope by said heater 10. y

'lhe heater 10 may be of any suitable form. It 1s preferably a wire l(flat, round, etc.) as

vshown in Figs.13, and 46-10 inclusive. The

:heater may be in sheet form, as the wire gauze sheet shown in Figs. 11 and 12. It isl conveniently in a form to surround', or in a form easily manipulated to surround a strand of hair wound `on a curler or rod 25, shown in Fig. 13. For example, the heater may be in the form of a helical coil 27, Figs. 1 and 3.

and 6 and 7. or a zigzag coil 26, Figs.v 8. 9 rand 10. or a iexible sheet 27. Figs. 11 and 12..,

The heater 10 is preferably associated with the envelope 15 or moisture container 20, or wlth both, but it can be made a separate part for repeated use with or ywithoutthe renewal ofI ntherparts. As shown in Figs. 6.7, 8 and 9, the heater 1s associated with and forms a composite article with.Y the moisture container. shown in Figs. 1 and 2. 10, 11 and 12, the beater 10. while immediately associated with the moisture carrier. is also associated with the envelope 15. which parts may constitute a composite article. The envelopev 15 and heater 10 shown in Figs. 10 and 11 may constitute by themselves a composite unit or article.

The moisture. holder or container 20 may be of anv suitable kind or form. As shown 1n Figs. 1-4, it may be in the form of a tube or tubes 30. 31 of absorbent material. such asV Y at 37, and which pad may contain theheater 10, and also chemicals 4() such as used inhair waving. The moisture carrieraLl of absorbent 'winding a sheet of waxed paper. lt

'of stiff cardboard as heretofore largel well understood. Thegupper end ofthe tube conducting than the heater,

45 may be closed in any suitable manner; by collapsing and tying; by a'plug, on by a wad of cotton, etc. As shown in Figs. 10, 11 and 12, the envelope may be in the form `of a sheet 47 of suitable character (as waxed paper) adapted to be wrapped around the prepared strand of haii" on .the curler or-rod 25.

As shown in Fig. 9,y the outside ply of the pad l(say the ply 36) may be made of impervious material, and when the "istripy is wound around the strand of hair, the outer. ply 36 will constitute an envelope forthe vapor produced by the heating.

The heating element 10 preferably has Aleads 50, 51 adapted to extend beyond the These are .preferably better in order not to become as hot as the heater, bein of asize not to excessively heat, or forme of copper envelope 15.

' for example, or copper coated (as shown in metal of higher resistance.

Figs. 1 and .3)l where the heater 10 is of a Moreover one or both of these leads 50,51, may be insulated where necessary or desirable, as by being cov-` ered by an insulating tube 55, Fig. 10, forexample, or the leads may be arranged on the article in such a way as not to require'insu-l lation to prevent touching. For example, the leads 50, 51, may be arranged on opposite sides of the tube 45, Fig. 1, and have the ends thereof bent over in such manner as to clamp the tube, as shown at 57, Fig. 1. In Fig. 11, the wire 50 is on the op osite s1de of the sheet 47 from the wire 51. n insulating strip 59 may be placed between the part 61 of the wire and the coil where lthe part 59 passes alongside of the coil inFig. 2.

- The device The ends of the wire may be connected toA feedwires 65, 66, in any suitable manner, as by clips 67 which grasp the ends of the' leads, asshown inFig. 14, or by a plug 68 (which may be of cork) having insulated segments 69 adapted to' be inserted in the end of a tube 45, for example, as shown'in Fig. 15.-

'The feed 1wires 65,' 66,-'are preferably connected toa device 7 0 of low 'otentiah so that shocks w1ll not be produced if `any part of the deviceis touched by, orcomes in contact with the person is also preferably of a char.

acter having a 'discharge rate approximately that required for normal `heating of each heater 10, `so that a fat spark will not be produced in case of a short circuit between parts o f the heater, thereby avoiding burning of (the lfair or parts used With'the heater. .For lexample, the part 70 may be a cell, or a secondary of a transformer rated to have a current output approximating that required for` the heater which it serves. Fig. 14 shows a number of. such devices 70 and envelopes 15 containing heaters, as usedl in waving a head of hair.

Thelocationof the electric heater in im.

tion of the hair, leaving the hair inA abetter after-condition than heretofore. Moreover, there is not the same necessity for transmission of the heat through the walls of so-called heaters? applied externally as heretofore and the heating up of comparatively large intervening masses before the moisture is heated.

Moreover ,in the preferred form of the invention any radiation to the outside'is from the inside of the envelope, so that all heat developed is utilized tothe best advantage.
